The entry-level model, known simply as Base, covers the truck basics. It's offered only as an extended cab. Standard features include a 2.5-liter inline four-cylinder engine (200 horsepower and 191 lb-ft of torque), rear-wheel drive, a six-speed automatic transmission, 16-inch steel wheels, air conditioning, vinyl upholstery and floor covering, and power windows.

You also get a rearview camera, a 7-inch infotainment system (GM's new Infotainment 3 system), Apple CarPlay and Android Auto, two USB ports, and a six-speaker sound system. It comes in both extended-cab and crew-cab body styles and adds cloth upholstery and carpeting.

The Work Truck at Dave Kirk Chevrolet can also be equipped with a few tech items, optional engines and exterior trim that make it feel less basic. Notable options include remote keyless entry, cruise control, an EZ Lift tailgate, a remote locking tailgate, and OnStar telematics and 4G LTE Wi-Fi hotspot connectivity.

From the WT level on up, you can get one of the Colorado's two optional engines: a 3.6-liter V6 (308 hp and 275 lb-ft) paired to an eight-speed automatic transmission or a 2.8-liter turbocharged four-cylinder diesel engine (181 hp and 369 lb-ft) paired to a six-speed automatic.

The LT at Dave Kirk Chevrolet adds most of the above items, plus 17-inch alloy wheels, a leather-wrapped tilt-and-telescoping steering wheel, an 8-inch touchscreen, satellite radio, and additional USB ports. LT options include heated front seats, automatic climate control, and forward collision and lane departure warning systems. For LT models and above, there's an available upgraded audio system and a navigation system.

The off-road-ready Z71 comes standard with most of the LT's optional equipment, plus all-terrain tires (instead of all-season tires), an off-road-oriented suspension, a locking rear differential, hill descent control and unique upholstery. If you want a real-deal off-roader, the ZR2 is your truck. The Chevy Colorado ZR2 has a raised suspension with special dampers, bigger all-terrain tires, fender flares, a special front and rear bumper for improved approach and departure angles, a spray-in bedliner (optional on other trims), and an electronically locking rear differential. The off-road ZR2 can be diesel-powered, but it comes standard with the V6.
